COMBINED WINDLASS AND WARPING-WINCH.

SPECIFICATION forming part of Letters Patent No. 696,394, dated April 1, 1902. Application filed January 25, 1902. Serial No. 91,259. (No model.)

To all whom it may concern.-

Be it known that I, JACOB R. ANDREWS, a citizen of the United States, residing at Bath, Sagadahoc county, Maine, have invented certain new and useful Improvements in a Combined "Windlass and \Varping Vinch, of which the following is a specification.

My invention relates to combined windlasscs and warping-winches; and it consists in the special construction hereinafter fully described, and illustrated in the accompanying drawings, which form part of this specification.

In the drawings, Figure 1 shows a side elevation of the engine and crank-shaft and main driving-shaft, with an end view of the windlass and winches. Fig. 2 is a plan view of the engine and winches.

Prior to my invention in windlasses of this type the warping has been done on heads placed on the ends of the Windlass shaft; but the windlasses are geared necessarily with a ratio of fifty or sixty to one, and the heads carried on the same shaft can have no greater speed than the Windlass. This speed, though sufficient for the Windlass, is slow for the winches, and I have sought to provide for increased speed of the warping-winch without great increase of cost or complication.

In the machines shown in the drawings the engine is located upon the deck below that upon which the Windlass is placed. The crank-shaft is shown at A of Fig. 1, which also shows the engines and their connections with said shaft. The shaft has a miterwheel 1 in mesh with another miter-wheel 2 on the main driving-shaft 3, and the lower bearing of which is supported upon a base 6, which supports the engine and its connection. The shaft 3 is vertical and extends through the deck on which the wind- Its upper end is in suitable lass is located.

bearings in the Windlass-frame and carries a worm 10, meshing with a worm-gear 4 011 the Windlass-shaft 5, on which are windlasses, as shown in Fig. 2. The pitch and proportions of this worm and gear are such as to give the required power and speed to the Windlassshaft, the ratio being, as aforesaid, from fifty or sixty to one. Instead of placing the winches, as heretofore, on the shaft 5 I have provided an independent shaft 6, which has its bearings in the frame of the Windlass, as shown more clearly in Fig. 2. This shaft carries upon its end winches 7 7 and contrally a worm-gear 8, which is in mesh with a second worm 9 on the shaft 3. This worm and gear are proportioned for greater speedfor example, four or five times greater than the shaft 5so that the proper speed may be given to the winches with the same speed of the shaft 3, and the warping may be done by this mechanism and by the same engine which operates the Windlass and running at the same speed. Any suitable clutch mechanism may be used if it be desired to run either the winches or the Windlass independently.

I claim In combination with the Windlass and the worm-gear upon its shaft, a shaft as 3 having a worm 10 in mesh with the gear upon the Windlass-shaft, a second worm 9 on the same shaft, a shaft 6 carrying winch-heads and providedwith a worm-gear S in mesh with the second worm on the main driving-shaft 3, all substantially as described.

In testimony whereof I afflx my signature in presence of two witnesses.

JACOB R. AND'REXVS.
